Comment 1 Sofer Athlan-Guyot 2023-02-20 19:45:48 UTC 
Note, that running:

    ansible -b -i overcloud-deploy/qe-Cloud-0/config-download/qe-Cloud-0/tripleo-ansible-inventory.yaml ovn_controller -mshell -a 'ovs-vsctl set open . external_ids:ovn-match-northd-version=false'

before update of the ovn-controller prevents the issue from happening.
